Gate Opener & Motor Repair
A gate operator fails one part at a time: power, control board, capacitor, motor, gear reduction, limit switches. When your gate stops responding, we trace that chain to the link that broke, and replace the part, not the machine.

What a Failing Operator Sounds Like
Operators rarely die without warning; each symptom below points to a different part of the machine.
- No response to remote, keypad, or exit loop.
- The motor hums or clicks, but the gate never moves.
- The gate opens partway, stops, and reverses without touching anything.
- Remotes only work from a few feet away.
- The gate works dry and goes dead in the rain.
- Nothing has worked since the night the power blinked.
Not all of these are opener problems: a sagging swing gate or a slide gate dragging through debris will stall a healthy motor, so we always check the hardware too. If the gate is stuck shut with a vehicle trapped behind it, call our 24/7 emergency gate repair line; we will walk you through the manual release while a truck is on the way.
How We Diagnose a Dead Operator
The diagnosis runs from the power coming in to the gate going out. Plenty of dead-opener calls end at a tripped GFCI or a failed transformer. If power is clean, we read the control board: scorched traces, swollen capacitors, a relay that clicks but passes no current, an accessory circuit dragged down by a shorted photo eye. When entry equipment is the real culprit, the job moves to our keypad, intercom and access control work.
From the board we move to the motor and drive. AC motors need a start capacitor to get the load turning, and a blown capacitor is among the most common, least expensive failures in the trade. Gear kits strip when the gate grows heavier to move: a slide gate grinding fir needles through its track, a sliding gate repair problem, or a leaf drooping on tired hinges, which belongs to swing gate repair. Fixing the motor without fixing the load schedules the next failure.
Last come the limits and the radio. Limit switches drift, so the gate overruns its stop or parks short of closed; receivers lose range as they age. All of it is testable; none of it requires guessing.
Stocked on the Truck
- Start and run capacitors
- Gear kits for popular residential operators
- Control boards for widely installed models
- Universal receivers and fresh remotes
- Photo eyes, loop detectors, surge arrestors
Every repair leaves the UL 325 safety devices tested and working, never bypassed.
The Operators We See Every Week
We service LiftMaster, DoorKing, Nice, Apollo, Viking, FAAC, BFT, US Automatic, Mighty Mule, Eagle, and Elite, plus older Linear and GTO units. Each brand has its habits.
| Operator family | Failures we find most often |
|---|---|
| LiftMaster | Stripped gear kits, aging backup batteries, board faults |
| DoorKing | Board and relay failures, limit drift, loop detector faults |
| Nice & Apollo | Solar charge controllers and batteries worn by short winter days |
| Viking | Control board and power supply failures |
| FAAC & BFT | Capacitors, control units, worn hydraulic seals |
| US Automatic & Mighty Mule | Solar charging problems, stripped gears, receiver range loss |
| Eagle & Elite | Capacitors, boards, drive wear on high-cycle gates |
If yours is not listed, call anyway; the components inside are more alike than the nameplates suggest.
Repair Guides by Brand
The brands we see most often each get their own page, covering the failures particular to that operator family and the parts we carry for it.
What Northwest Winters Do to Control Boards
Winter outages are the biggest killer of gate control boards on both sides of the Columbia. The board usually survives the lights going out; the surge when power returns is what burns it. We replace surge-damaged boards every January in Portland and across Clark County in Vancouver, and now fit a surge arrestor on every board we replace.
The wet season causes quieter failures: eight months of drizzle finds every cracked conduit fitting, the source of the works-until-it-rains symptom. On the acreage around Battle Ground, solar operators fall short in December; the fix is a battery, not the motor. A fall inspection under our gate maintenance plans catches most of this before the first storm.
When an operator is truly past saving, whether a discontinued board, corroded housing, or undersized motor, we say so plainly and lay out what a replacement operator or new gate installation involves.
Gate Opener Repair FAQ
My opener hums but the gate does not move. What failed?
A hum means the motor has power but cannot turn the load: usually a failed start capacitor, or a stripped gear kit on residential units. On manual release we push the gate by hand: if it drags, the hardware is stalling a healthy motor.
Is it worth repairing an older opener, or should I replace it?
If boards and gear kits are still made for your model, repair is usually the smaller job. When the board is discontinued or the housing has corroded through, we show you the failed part and let the facts make the case.
Why did my opener stop working after a power outage?
The damage usually happens when power returns: the restoration surge burns relays and traces on the control board. Sometimes re-teaching the limits is enough; a scorched board needs replacement, plus a surge arrestor so it does not happen twice.
Can you replace lost remotes or fix a receiver that stopped responding?
Yes. We program new remotes, erase lost ones, and replace receivers whose range has collapsed. When a receiver is obsolete, we retrofit an external receiver that accepts current transmitters, a small job next to replacing the operator.
Do you carry parts on the truck, or will I need a second visit?
The trucks stock capacitors, gear kits, universal receivers, photo eyes, and boards for widely installed models. Most opener repairs finish in one visit; if a board must be ordered, we say so before any work begins.
